Method Details

datatypes

private static Map<QName, CoreDatatype.XSD> datatypes()

parseCalendar

private static XMLGregorianCalendar parseCalendar(String label)

getLabel

public String getLabel()

Description copied from interface: Literal

Gets the label (the lexical value) of this literal.

Returns:

The literal's label.

getLanguage

public Optional<String> getLanguage()

Description copied from interface: Literal

Gets the language tag for this literal, normalized to lower case.

Returns:

The language tag for this literal, or Optional.empty() if it doesn't have one.

getDatatype

public IRI getDatatype()

Description copied from interface: Literal

Gets the datatype for this literal.

If Literal.getLanguage() returns a non-empty value than this must return rdf:langString. If no datatype was assigned to this literal by the creator, then this method must return xsd:string.

Returns:

The datatype for this literal.

calendarValue

public XMLGregorianCalendar calendarValue()

Description copied from interface: Literal

Returns the XMLGregorianCalendar value of this literal. A calendar representation can be given for literals whose label conforms to the syntax of the following XML Schema datatypes: dateTime, time, date, gYearMonth, gMonthDay, gYear, gMonth or gDay.

Specified by:

calendarValue in interface Literal

Overrides:

calendarValue in class AbstractLiteral

Returns:

The calendar value of the literal.

getCoreDatatype

public CoreDatatype getCoreDatatype()

Description copied from interface: Literal

CoreDatatype is an interface for natively supported datatypes in RDF4J. This includes, among others, the XML Schema datatypes and rdf:langString. CoreDatatypes are implemented as enums and more performant and convenient to work with than IRI-based datatypes. The constant

invalid @link

{@link CoreDatatype#NONE)

} is used to represent a datatype that is not one of the supported core datatypes.

Returns:

The CoreDatatype or

invalid @link

{@link CoreDatatype#NONE)

} if the datatype matches none of the core datatypes. This method will not return null.
